Fortress of Spears: Empire III (Empire series). The Romans have vanquished the rebel alliance, leaving Calgus, Lord of the Northern Tribes, the prisoner of the chieftains he once led. Marcus Aquila - burning for revenge on an enemy army that has killed one of his best friends - is part of the select group of infantry chosen to go north with the Petriana cavalry and take the fort before the rebel army can reach it.
